Story

The New Worst Witch

During his stay at Cackle's he studied hard for the "Wiz of the Year Competition" which was being hosted at the academy. Students were oblivious to the fact that Constance Hardbroom was the aunt of Artemis and were shocked to find out. He later helped Henrietta Hubble brew a Transgenderification Potion for Mona Hallow to bypass the "rules" that only wizards were allowed to enter the competition.

He later lost the "Wiz of the Year Competition" and Mona Hallow won; however, even though the prize was a place at a summer camp, his aunt bribed the camp to give him a place anyway.
